FLUID-GAGE.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed August 13, 1914. Serial No. 856,629.

To all whom it may concern Be it known that I, HERBERT HAs'rmos,

citizen of the United States, residing at Brighton, in the county, ofMonroe and State of New York, have invented .certain new and usefulImprovements in Fluid- Gages, of which the following is a specification.

. My invention relates to improvements in fluid gages for constantlyindicating the depth or amount of fluid in a receptacle and particularlyadapted for use in cowl tanks of automobiles, with the indicator mountedupon the instrument board or dash of the car, also for use upon tanksvariously mounted and for varied service.

' The gage of my present invention, is an improvement over the gage forwhich'Letters Patent were issued to me on September 24th, 1912, Number1039280, in that the indicator in my present invention-is desi ed toindicate, durin the process of filing, the amount of liquid in the tankas well as at other times.

Other objects of my invention are; the combining of the gage. with thefiller fixture of a tank; the accomplishing of a design I which adaptsthe gage to mounting so that tank sullen.

the visual to the indicator, may be placed upon the instrument board;the simplifying of the gage to more economical manufacture. Y

r The above objects in the spirit of my invention, might be attained inmany differout ways and combination of parts. I prefor to show however,the construction illustratedin the drawings, in which- Figure 1 is alongitudinal view partly in section, taken through the center of thegage and shows broken sections of the tank to which it is attached andalso of the cowel and instrument board. Fig. 2 is a similar view of agage constructed in ac cordance with my invention but in .slightlydifferent form from that shown in Fig. 1 and shows a portion of the gageas broken away. Fig. :3 is a partial plan view of the gage shown in Fig.1 with the cap removed. Fig. 4 is a detached, broken view of the visualwindow of the gage shown in Fig. 2. Fig. 5 is a plan View of the floatshown in Fi 1. ,Fig. 6 is a longitudinal view partia ly in section, of9. ga .e embodying my invention, showing anot r modification in form andmethod of attaching to the ceive the closure or cap -2- and the lower'end is enlarged at -1" and into this enlarged portion is inserted theglass crystal 3- which covers the opening in the plate 4 through whichthe characters --5- on the indicator 5-, are visible. The outercircumference of the portion -1"- merges into the cylindrical portion 1-which may be provided with an integral flange -1 by means of which thebody may be suitably fastened to the tank, as is represented in Figs. 1and 2, in which cases the tank is provided with a collar --6 flangedat.--6 and this flange is reinforced on the under side by the pinch ring-7- and the screws -8 being threaded into of the tank collar 6. Acrossthe inner circumference of the portion 1 of the body -1., is a bar 1--which is perforated t'o receive the two ends -9" of the U shaped floatguide 9 and is also erforated to support the revoluble spiral s aft 10near its upper end. Extending across the inside of the body and abovetheindicator, are guard spokes 1- for protecting the indicator from damagefrom above and at the same time allowing space for the free passage offluid into the tank.

The float guide -9 is provided with a bearing seat -9- at the center ofits bottom bar and the upper ends of the ''de are suitably fixed to thebar -'1- 0 the gage body. The float -11 which may be of any suitablematerial, is provided at the top with the bearing plate -'12- whichongages the guide -9 to keep, the float from turning and this plate isperforated at the center to conform to the cross-sectional shape of thespiral shaft .--10- so that as the float rises and falls this platecauses the spiral shaft to turn. The float is also provided with a lowerbearing plate -13- which is perforated at the center to allow the spiralshaft to slide fneely therethrough and serves as a guide to keep thefloat 'm this ring, .are adapted to draw the gage alinement with theshaft to prevent cramp- 4 the characters appear at the center 4 of theplate 4--,- they indicate the amount of liquid remaining in the tank.The indlcator is also provided with spokes --5"- forming openings in theindicator through which the liquid may pass when the tank is beingfilled. I

The glass crystal -3 is securely held in the gage-body by the internallyflanged ring ,14, which is firmly fitted in the seat .-1-- provided forit in the body, and holds the 'glass under the flange portion of thering and the glass in turn, presses against the plate 4 to hold it incorrect position. The plate 4 could-be. done away with by coating theunderside of the glass -3- with an opaque coating except where it isdesired to leave the visual open- IIaving thus described my inventionwhat I claimas new and desire to secure by Letters Patent -is- 1. In afluid gage a body provided with a fluid passage and also provided withan opening through which the indicator is visible; a float guide securedto. said body; a float slidably mounted upon said guide; a shaft adaptedto be turned by said float; an

' indicator provided with fluid-passage openings mounted upon said shaftand provided with indicating characters.

2. In a fluid gage afloat; a float guide; a

shaft adapted to be turned by the floa't; a

' member provided with indicating characters mounted upon said shaft;and a gage body,

adapted to form a fluid passage and provided with an opening throughwhich said characters are visible and with means for supporting saidguide and shaft and with means for protecting said indicating member.

3. In a fluid age a float; a guide for said float; a shaft adapted to beoscillated by the float; an indicator mounted on said shaft providedwith indicating characters and with fluid passa e openings; a gage bodyprovided with a uid passage, a'support for said guide and shaft, and anopening through which said indicating characters are visible; and' atransparent closure for said opening.

spiral shaft -l0 has a pivot por- 4. In a fluid gage a body forming afluid ,passage and provided with an indicator oblserving opening, arevoluble indicator supguide; a float; a revoluble indicator adapted tobe turned by the float and providedwith indicating means; a closure forsaid fluid passage and a closure for reading opening.

6. In a fluid gage a body forming a'fluid passage and adapted to supporta float guide said indicator;

and indicator; a U shaped guide for a float attached there-to andsupporting one end of a revoluble shaft; a revoluble shaft; rovided withindicating characters; a oat adapted to revolve said shaft; and aclosure for said fluid passage.

7. In a..fluid gage a hollow, cylindrical gage body forming a fluidpassage and pro! vided within the passage with a support for a. floatguide and a revoluble member and with means for protecting the revolublemember and also provided within the wall there-of with an openingthroughwhich a portion of the revoluble member is visible.

8. In a fluid gage a hollow, cylindrical gage body forming a fluidpassage and provided within the passage with a support for a float guideand a revoluble member and with means for protecting the revolublemember and also provided, within the wall there-of, with an openingthrough which a portion of the revoluble member is ,visible; 1

a transparent closure for said opening; a float guide; a float; anindicator adapted to foo its
